pyral - A Python toolkit for the Rally REST API

The pyral package enables you to push, pull and otherwise wrangle the data in your Rally subscription using the popular and productive Python language. The pyral package provides a smooth and easy to use veneer on top of the Rally REST Web Services API using JSON.

Getting started

Rally has created a Python package that you can quickly leverage to interact with the data in your subscription via the REST web services API. You can create, read, update, and delete the common artifacts and other entities via the Python toolkit for Rally.

Download

Files are available at the download page .

The git repository is available at

Installation

If you want to pull down the latest release from standard Python package repository (pypi.python.org) and install the package, the easiest way is to use pip, the Python package installation utility.:

pip install pyral

Alternatively, if you've got the tar.gz or zip distribution on hand, as long as you've satisfied the dependency requirement on the requests package, you can use the setup mechanism. Obtain the requests package and install it according to that package's directions. Use of requests-2.28.x or better is recommended for use with pyral. The requests package can be found via the Python Package Index site (). The most recent release of pyral (1.6.0) has been tested using requests 2.31.0.

Unpack the pyral distribution file (zip or tar.gz) and then install the pyral package.

python setup.py install

Use whatever setup options you need for your particular Python environment.

Sanity Check

Fire up a command line Python interpreter. Attempt to import the relevant packages.

$ python
Python 3.11.5 [other Python interpreter info elided ...]
>> import requests
>> import pyral
>> pyral.__version__
(1, 6, 0)

30 second highlight

Since Python is a very flexible and extensible language, we were able to make access to the object model extremely simple. For example, if you have a a UserStory instance returned by a pyral operation assigned to the name story, the following code iterates over the tasks.

for task in story.Tasks:
   print task.Name

There is no need to make a separate call to fetch all the tasks for the story. When you follow domain model attributes in the Python code, the Python toolkit for Rally REST API machinery automatically loads in the necessary objects for you.

Full Documentation

The complete documentation for the Python toolkit for Rally REST API is in the doc/build/html subdirectory in the repository. The rendered version of this is also available at

Sample code

Common setup code :

import sys
from pyral import Rally, rallyWorkset
options = [arg for arg in sys.argv[1:] if arg.startswith('--')]
args    = [arg for arg in sys.argv[1:] if arg not in options]
server, user, password, apikey, workspace, project = rallyWorkset(options)
rally = Rally(server, user, password, apikey=apikey, workspace=workspace, project=project)

Show a TestCase identified by the FormattedID value.
Copy the above boilerplate and the following code fragment and save it in a file named gettc.py

query_criteria = 'FormattedID = "%s"' % args[0]
response = rally.get('TestCase', fetch=True, query=query_criteria)
if response.errors:
    sys.stdout.write("\n".join(errors))
    sys.exit(1)
for testCase in response:  # there should only be one qualifying TestCase  
    print "%s %s %s %s" % (testCase.Name, testCase.Type,  
                           testCase.DefectStatus, testCase.LastVerdict)

• Run it by providing the FormattedID value of your targeted TestCase as a command line argument

  > python gettc.py TC1184

Get a list of workspaces and projects for your subscription
Copy the above boilerplate and the following code fragment and save it in a file called wksprj.py

workspaces = rally.getWorkspaces()
for wksp in workspaces:
    print "%s %s" % (wksp.oid, wksp.Name)
    projects = rally.getProjects(workspace=wksp.Name)
    for proj in projects:
        print "    %12.12s  %s" % (proj.oid, proj.Name)

• Run the script

  > python wksprj.py

Create a new Defect
Copy the above boilerplate and the following code fragment and save it in a file called crdefect.py

proj = rally.getProject()

# get the first (and hopefully only) user whose DisplayName is 'Sartorious Submitter' 
user = rally.getUserInfo(name='Sartorius Submitter').pop(0) 

defect_data = { "Project" : proj.ref, "SubmittedBy" : user.ref, 
                "Name" : name, "Severity" : severity, "Priority" : priority,
                "State" : "Open", "ScheduleState" : "Defined", 
                "Description" : description }
try:
    defect = rally.create('Defect', defect_data)
except Exception, details:
    sys.stderr.write('ERROR: %s \n' % details)
    sys.exit(1)
print "Defect created, ObjectID: %s  FormattedID: %s" % (defect.oid, defect.FormattedID)

• Run the script

  > python crdefect.py <Name> <severity> <priority> > <description>

  making sure to provide valid severity and priority values for your workspace

Update an existing Defect
Copy the above boilerplate and the following code fragment and save it in a file called updefect.py .

defectID, customer, target_date, notes = args[:4] 
# target_date must be in ISO-8601 format "YYYY-MM-DDThh:mm:ssZ"

defect_data = { "FormattedID" : defectID, 
                "Customer"    : customer, 
                "TargetDate"  : target_date, 
                "Notes"       : notes 
              } 
try:
    defect = rally.update('Defect', defect_data)
except Exception, details:
    sys.stderr.write('ERROR: %s \n' % details)
    sys.exit(1)

print "Defect %s updated" % defect.FormattedID

• Run the script

  > python updefect.py <Defect FormattedID> <customer> > <target_date> <notes text...>

Config Options

The pyral package uses a priority chain of files, environment variables and command line arguments to set the configuration context when an instance of the Rally class is created. See the complete documentation for detailed information on this mechanism. Here's a brief description of how you can specify a configuration when you create an instance of the Rally class.

Configuration file settings

The item names in config files are case sensitive.

Fixed defect in SchemaItemAttribute where > self._allowed_values_resolved was not always set. Fixed defect in > RallyRestResponse in __repr__ method where on a response that has > no qualifying items an attempt is made to get the Results out of the > returned response without going through the QueryResult key. > > 1.2.3
> Fixed restapi.py Rally.getAllowedValues method to accommodate custom > fields Allow attribute payload for put and post to have a list of > pyral.Entity instances as values for an attribute that is of type > COLLECTION. > > 1.2.2

Corrected handling of allowedValues for attributes when the > single allowedValue is a boolean value. Added an allowedValues.py > example script. > > 1.2.0
> Support for Python 3.5.x Begin deprecation sequence for pinging the > Rally server before the connection attempt, initially with this > version, allow option on instantiation to bypass ping. Added ability > to rankAbove, rankBelow, rankToTop, rankToBottom for an Artifact. > Fixed defect where user has no default workspace or project. > > addAttachment now correctly handles binary file, attachment size limit > increased to 50MB to match Agile Central limit. Exception generated > when running getAllUsers when credentials are for non > Subscription/Workspace Administrator has been fixed. Added ability to > work with a single Workspace, which has beneficial performance effect > for Subscriptions with a large number of Workspaces. Modified internal > attribute handling to limit calls to get attribute's allowed values to > qualifying attribute types. Added examples/updtag.py script. > > see the VERSIONS file for information pertaining to older releases
